HENRY LOVE, OF CREUSOT, FRANCE.

DOUBLE-ACTION REVOLVER.

SPECIFICATION forming part of Letters Patent No. 445,511, dated January2'7, 1891. Application filed September 30. 1890. Serial No. 366,625 (Nomodel.)

To aZZ whom it 72mg concern.-

Be it known that I, HENRY LOVE, of Creusot, in the Republic of France,have invented a new useful Improvement in Double-Action Revolvers, whichimprovement is fully set forth in the following specification.

This invention relates to the lock mechanism of double-action revolversin which the movement of the trigger under pressure of the finger servesboth to raise the hammer to full-cock and also to release the same anddischarge the weapon.

In the most common type of self-cccking revolvers the hammer is not set.or arrested at full-cock, but is raised and released by a continuedpressure upon the trigger. It is difficult to secure accuracy of aimwith this kind of a revolver, owing to the fact that the user is notwarn ed of the approach of the point of discharge, and because, also,during all the time of cooking and firing a verystrong pull must beexerted upon the trigger so as to overcome the force of the mainspring.

According to the present invention the lock mechanism is so constructedthat when the hammer is fully drawn back it is arrested and set by thesear at full-cock, and the trigger is at once relieved of the pressureof the mainspring. The hammer is dropped by a further slight motion ofthe trigger. Thus the pressure required to drop the hammer is whollyindependent of the force of the mainspring, and may be adjusted to thatamount which conduces to the most efficient use of the weapon, whichamount varies according to the purpose for which the revolver isdesigned.

I am aware that it is not broadly new to provide a double-actionrevolver with mechanism enabling it to be set at full-cock by a pull onthe trigger and released by a further pull 5 but the means hereinafterdescribed are believed to accomplish this result in a more efficient andreliable manner than any heretofore devised. In one prior lock mechanismof this type the hammer, when at full-cock, is engaged by a notch in thetrigger itself, and consequently bears with its full force on thetrigger. In another form heretofore devised the hammer-lifter is thrownout of engagement with the hammer, leaving the lat ter in firingpositionas soon as it is set at fullcock, the sear being tripped by contacttherewith of a rigid projection of the trigger.

According to the present invention the lifter remains in position toprevent the fall of the hammer until the trigger is pulled for thepurpose of discharging the weapon, when the lifter is thrown out ofengagement with the hammer. This may be accomplished in various ways.Preferably it is effected through the action of the tripper, which atthis moment makes contact with the sear. This tripper, which is carriedby the trigger, is not rigidly connected therewith, but is pivotedthereon and pressed in the direction of the sear by a spring.

In the accompanying drawings, which form part of this specification,Figure I is a side elevation of the lock mechanism of a doubleactionrevolver equipped with my improvements, the hammer being down. Fig. IIis a similar view showing the parts in the position they occupy when thehammer is about to be released by the sear. Fig. III shows the triggerin detail; Fig. IV, the tripper; Fig. V, the lifter, and Fig. VI thesear.

The invention is shown as applied to an or dinary French army revolver.I have, however, applied it to other revolverssuch as the well-knownSmith d: \Vessonwithout changing the essential features of theinvention. Simple modifications in the shape and arrangement of some ofthe parts are all that is necessary to effect such application.

A represents the hammer, which is pivoted at a and provided with theusual half-cock point Z) and full-cock point (Z.

B is the mainspring; O, the click for rotating the chambered cylinder D;E, the trigger, and F the sear. These parts, except in the particularshereinafter pointed out, are of ordinary construction.

G is the lift-er for cooking the hammer. It is pivoted at g to thetrigger E, which is pivoted to the case of the lock mechanism at e. Thelifter has two shoulders or catches 7 and 8. The shoulder 7 acts toraise the hammer by engagement with the notch 9, being normally held incontact with the edge of the hammer by the pressure of a light spring2', which for convenience is in this case carried by the click 0. Theshoulder 8 normally remains in the notch 10 of the hammer, and

"prevents return. of the trigger so long as the hammer is in a raisedposition. In these respects the lifter is of known form.

The movable tripper K is pivoted to the trigger on the same pin as thelifter. It is disposed and has a limited play in a mortise 12 in thetrigger. (See Fig. III.) It is normally pressed in the direction of thesear by a spring 7;, which, for a purpose hereinafter explained, isstronger than the lifter-spring i. The motion of the tripper in thisdirection is limited by a stop-pin 13. This tripper has the generalshape of an L. Its short arm Zis the part which at the proper momentmakes contact with and trips the sear. At its upper end near the centerof oscillation is a shoulder n, adapted at the proper time to engage theshoulder 0 of the lifter G.

The scar F has the usual catch f for engaging thefullcock and half-cockpoints I) and d of the hammer, and is pressed against the latter by thesear-spring 14. On its forward end the sear has a tongue 0, which is inthe same plane as the tripper and adapted to come in contact therewith,as shown in Fig. II.

The trigger is returned to its normal position after firing by thetrigger-sprin M.

In operation, the parts being in their nor mal positions, Fig. I, theuser to cook the hammer pulls firmly on the trigger, as in firing. Asthe trigger is drawn back, the lifter turns the hammer on its centeruntil the catch f in the sear engages the fullcock point or shoulder andretains the hammer at full-cock against the pressure of the mainspring.During this movement the shoulders at and 0 on the tripper and lifter,respectively, have been approaching each other until finally they comein contact, as shown in Fig. II. At this moment, also, the tongue 0 ofthe sear is in contact with the lower end of the tripper. It is to benoted that when the hammer rests at full-cock the catch 7 of the lifterG still prevents the falling of the hammer, even if released by thesear, though the hammer no longer rests on this catch. \Vhen now, theparts being in the position shown in Fig. II, a further pull is exertedon the trigger for the purpose of firing, the tripper does not at oncetrip the sear, because the resistance of the lifter G causes the tripperto retreat farther into the mortise of the trigger, compressing itsspring 7.: until the force of the latter (which, as stated above, isstronger than the litter-spring) raises the lifter. This takes placebefore the tripper finally tilts the scar and permits the hammer tofall. As soon as the pressure of the finger upon the trigger is releasedthe trigger-spring M returns the trigger, and with it the litter andtripper, to the positions shown in Fig. I.

It will be observed that the self-cocking mechanism herein describeddoes not in any way interfere with the setting of the hammer atfull-cock or half-cock by hand in the usual way.

I claim as my invention- 1. In a double-action revolver, thecombination, with the hammer, the trigger, the sear, and devices forraising the hammer by the motion of the trigger until caught at fullcockby the sear, of a movable spring-mounted tripper carried by the triggerand disposed in the plane of the sear so as to trip the same upon afurther motion of the trigger, substantially as described.

2. The combination of the hammer, the trigger, the lifter carried by thetrigger and engaging with the hammer, the scar, and the tripper pivotedto the trigger and adapted to trip the sear by further motion of thetrigger after the hammer has been set at full-cock, substantially asdescribed.

3. The combination, with the hammer, trigger, and sear, of the liftercarried by the trigger, and the sear-tripper pivoted to said trigger andadapted to move the lifter out of engagement with the hammer beforetripping the sear, substantially as described.

4. The combination, with the hammer, trigger, and sear, of the lifterand its spring, the tripper pivoted on the trigger, and thetripper-spring arranged to press the tripper toward said scar and lifterwhen the hammer is cocked, said spring having greater strength than thelifter-spring, the tripper being arranged to come in contact with thelifter and hold it away from the hammer before tripping the sear,substantially as described.

In testimony whereof I have signed this specification in the presence oftwo subscribing witnesses.

HENRY LOVE.
